I/O Modules with Barriers

The primary purpose of the 3500/42M monitor is to provide 1) machineryprotection by continuously comparing current machine vibration againstconfigured alarm setpoints to drive alarms and, 2) essential machine vibrationinformation to both operator and maintenance personnel. Alarm setpoints areconfigured using the 3500 Rack Configuration Software. Alarm setpoints can beconfigured for each active proportional value and danger setpoints can beconfigured for two of the active proportional values.

When shipped from the factory, the 3500/42M is delivered unconfigured. Whenneeded, the 3500/42M can be installed into a 3500 rack and configured toperform the required monitoring function. This lets you stock a single monitor foruse as a spare for many different applications.

2.1 Triple Modular Redundant (TMR) DescriptionWhen used in a TMR configuration, 3500/42M monitors and Proximitor/SeismicTMR I/O Modules must be installed adjacent to each other in groups of three.When used in this configuration, two types of voting are employed to ensureaccurate operation and to avoid single point failures.

The first level of voting occurs on the TMR Relay Module. With this voting, theselected alarm outputs for the three monitors are compared in a 2 out of 3method. Two monitors must agree before the relay is driven. Refer to the3500/32 & 34 Relay Module Operation and Maintenance Manual for moreinformation on this voting.

Internal Proximitor BarrierI/O Module, InternalTermination, refer toSection 4.3

Internal Prox/SeismicBarrier I/O Module,Internal Termination,refer to Section 4.3

Internal Seismic BarrierI/O Module, InternalTermination, refer tosection 4.3


6

The second type of voting is referred to as "Comparison" voting. With this typeof voting, the proportional value outputs of each monitor in the group arecompared with each other. If the output of one monitor differs from the output ofthe other monitors in the group by a specified amount, that monitor will add anentry to the System Event list. Configure comparison voting by settingComparison and % Comparison in the Rack Configuration Software.

Comparison: The enabled proportional value of the TMR monitor group that isused to determine how far apart the values of the three monitors can be toeach other before an entry is added to the System Event List.

% Comparison: The highest allowed percent difference between the middlevalue of the three monitors in a TMR group and the individual values of eachmonitor.

For TMR applications, two types of input configurations are available: bussed ordiscrete. Bussed configuration uses the signal from a single nonredundanttransducer and provides that signal to all modules in the TMR group through asingle 3500 Bussed External Termination Block.

Discrete configuration requires three redundant transducers at eachmeasurement location on the machine. The input from each transducer isconnected to separate 3500 External Termination Blocks.

2.2 Available DataThe Proximitor/Seismic Monitor returns specific proportional values dependentupon the type of channel configured. This monitor also returns both monitor andchannel statuses which are common to all types of channels.

2.2.1 StatusesThe following statuses are provided by the monitor. This section describes theavailable statuses and where they can be found.

Monitor Status

OKThis indicates if the monitor is functioning correctly. A not OK status isreturned under any of the following conditions:

Module Hardware Failure

Node Voltage Failure

Configuration Failure

Transducer Failure

Slot ID Failure

Keyphasor Failure (if Keyphasor signals are assigned to channel pairs)

Channel not OK

If the Monitor OK status goes not OK, then the system OK Relay on the RackInterface I/O Module will be driven not OK.


7

Alert/Alarm 1

This indicates whether the monitor has entered Alert/Alarm 1. A monitor willenter the Alert/Alarm 1 state when any proportional value provided by themonitor exceeds its configured Alert/Alarm 1 setpoint.

Danger/Alarm 2

This indicates whether the monitor has entered Danger/Alarm 2. A monitorwill enter the Danger/Alarm 2 state when any proportional value provided bythe monitor exceeds its configured Danger/Alarm 2 setpoint.

Bypass

This indicates when the monitor has bypassed alarming for one or moreproportional values at a channel. When a channel bypass status is set, thismonitor bypass status will also be set.

Configuration Fault

This indicates if the monitor configuration is valid.

Special Alarm Inhibit

This indicates whether all the nonprimary Alert/Alarm 1 alarms in theassociated monitor channel are inhibited.

The Channel Special Alarm Inhibit function is active when:

- The Alarm Inhibit contact (INHB/RET) on the I/O Module is closed(active).

- A Channel Special Alarm Inhibit software switch is enabled.

Channel Status

OK

This indicates that no fault has been detected by the associated monitorchannel.

There are three types of channel OK checking: Transducer Input Voltage,Transducer Supply Voltage, and Keyphasor OK. Keyphasor OK only affectschannel pairs that have Keyphasor signals assigned to them. A channel OKstatus will be deactivated if any of the three OK types goes not OK.

Alert/Alarm 1

This indicates whether the associated monitor channel has enteredAlert/Alarm 1. A channel will enter the Alert/Alarm 1 state when anyproportional value provided by the channel exceeds its configured Alert/Alarm1 setpoint.

Danger/Alarm 2

This indicates whether the associated monitor channel has enteredDanger/Alarm 2. A channel will enter the Danger/Alarm 2 state when anyproportional value provided by the channel exceeds its configuredDanger/Alarm 2 setpoint.


8

Bypass

This indicates that the channel has bypassed alarming for one or more of itsproportional values. A channel bypass status may result from the followingconditions:

- A transducer is not OK, and the channel is configured for Timed OKChannel Defeat.

- The Keyphasor associated with the channel has gone invalid causing allproportional values related to the Keyphasor signal (for example 1XAmplitude, 1X Phase, Not 1X, ...) to be defeated and their associatedalarms bypassed.

- The monitor has detected a serious internal fault.

- A software switch is bypassing any channel alarming function.

- The Special Alarm Inhibit is active and causing enabled alarms not to beprocessed.

Special Alarm Inhibit

This indicates whether all the nonprimary Alert/Alarm 1 alarms in theassociated monitor channel are inhibited.

The Channel Special Alarm Inhibit function is active when:

- The Alarm Inhibit contact (INHB/RET) on the I/O Module is closed(active).

- A Channel Special Alarm Inhibit software switch is enabled.

Off

This indicates whether the channel has been turned off. The monitorchannels may be turned off (inactivated) using the Rack ConfigurationSoftware.

17

Notes:

The alarming hysteresis for all channel configurations for a 42M Monitor is 1/64of Full Scale. When a channel exceeds an alarm setpoint, it must fall back belowthe setpoint less the hysteresis before it can go out of alarm. For example,consider a channel configuration with a 0–10 mils full scale and an alarm setpointat 6 mils as illustrated below:

The hysteresis = 10 mils/64 = 0.16 mils. The channel input must fall below 6 mils- 0.16 mils (5.84 mils) before the channel is out of alarm.

3.1.2 Radial Vibration Channel OptionsThis section discusses the Configuration Considerations and the Rack ConfigurationSoftware screens associated with the Radial Vibration Channel.

3.1.2.1 Radial Vibration Channel Configuration ConsiderationsConsider the following items before configuring a Radial Vibration Channel:

- Internal Barrier I/O Modules and External barriers are not currently supported with7200 11 mm or 14 mm, or 3000 Proximitors, or the 3300 16 mm HTPS.

- When "No Keyphasor" is selected, the 1X Amplitude (Ampl) and Phase Lag, 2XAmplitude (Ampl) and Phase Lag, Not 1X Amplitude (Ampl), and Smax Amplitude(Ampl) can not be selected.

- If a Keyphasor channel is selected, a Keyphasor Module must be installed in therack.

- The full scale options allowed for each proportional value is dependent upon thetransducer type.

- If a Non-Standard transducer is selected, the setpoint OK limits are set to ±1 voltfrom the Upper and Lower OK limits that are selected.


18

- There are two selections for 3000 Series transducers:

3000(-24V) ProximitorSelect this option when connecting a 3000 Series proximitor directly to a3500 monitor. A default scale factor of 285 mV/mil will be selected. Thismay be adjusted ±15 %. Note that the buffered transducers on the front ofthe monitors and to the Data Manager are not compensated and should beinterpreted at 285 mV/mil.

3000(-18V) ProximitorSelect this option when connecting a 3000 Series proximitor directly to a3500 monitor, but supplying proximitor power from an external 18 volt source.A default scale factor of 200 mV/mil will be selected. This may be adjusted±15 %. Note that the buffered transducers on the front of the monitors and tothe Data Manager are not compensated and should be interpreted at 200mV/mil.

- Setpoints may only be set on proportional values which are enabled.Monitors must be configured in channel pairs (for example, Channels 1 and 2 may

be configured as Radial Vibration and Channels 3 and 4 may be configured asThrust Position).

- When a full-scale range is modified, the setpoints associated with this proportionalvalue should be readjusted.

- It is best to set the Scale Factor value and the Trip Multiply value before the ZeroPosition value.

- 3000 (-18V), 3000 (-24V), and 3300 RAM Proximitors have limited linear ranges.Therefore, you should use caution when selecting the Full-scale range of theDirect, 1X Amplitude (Ampl), 2X Amplitude (Ampl), Not 1X Amplitude (Ampl) andSmax Amplitude (Ampl) PPLs. Full-scale value x Trip Multiply should not exceedthe linear range of the transducer.


19

3.1.2.2 Radial Vibration Channel Configuration OptionsThis section describes the options available on the Radial Vibration Channelconfiguration screen.

Timed OK Channel DefeatThis prevents a channel from returning to an OK status until that channel'stransducer has remained in an OK state for 30 seconds. This feature is alwaysenabled in the Radial Vibration Channels. The option protects against false tripscaused by intermittent transducers.

CP ModSelecting the CP Mod button Channel Options Dialog Box, allows a Custom channelconfiguration to be downloaded to the monitor. Custom configuration data is storedin a Custom Products Modification File. Custom Products Modification files followthe naming convention <modification #.mod>. These files must be located in the\3500\Rackcfg\Mods\ directory. When a CP Mod file is selected, a window isdisplayed which describes the function of the modification. CP Mod files areavailable through Bently Nevada's Custom Products Division. Contact your localBently Nevada Sales Representative for details.

Reference InformationThese fields contain information that indicates which module you are configuring.

ChannelThe number of the channel being configured (1 through 4).


Rack TypeIdentifies the type of Rack Interface Module installed in the rack (Standard orTMR).

EnableAn enabled proportional value specifies that the value will be provided by thechannel ( enabled, disabled).

DirectData which represents the overall peak to peak vibration. All frequencies withinthe selected Direct Frequency Response are included in this proportional value.

GapThe physical distance between the face of a proximity probe tip and the observedsurface. The distance can be expressed in terms of displacement (mils,micrometres) or in terms of voltage. Standard polarity convention dictates that adecreasing gap results in an increasing (less negative) output signal.

1X AmplIn a complex vibration signal, notation for the amplitude component that occursat the rotative speed frequency.

1X Phase LagIn a complex vibration signal, notation for the phase lag component that occursat the rotative speed frequency.

2X AmplIn a complex vibration signal, notation for the amplitude component having afrequency equal to two times the shaft rotative speed.

2X Phase LagIn a complex vibration signal, notation for the phase lag component having afrequency equal to two times the shaft rotative speed. 2X phase lag is theangular measurement from the leading or trailing edge of the Keyphasor pulse tothe following positive peak of the 2X vibration signal.

Not 1X Ampl

In a complex vibration signal, notation for the amplitude component that occurs atfrequencies other than rotative speed.

Smax Ampl

Single peak measurement of unfiltered XY (orthogonal) probes, in the measurementplanes, against a calculated "quasi zero" point. Only one Smax Ampl value isreturned per channel pair (channel 1 or channel 3).

Full Scale Range

Each selectable proportional value provides the ability to set a full scale value. If thedesired full scale value is not in the pull down list, then the custom selection can bechosen.

Clamp ValueThe value that a proportional value goes to when that channel or proportionalvalue is bypassed or defeated (For example when a problem occurs with thetransducer). The selected value can be between the minimum and maximumfull-scale range values. (1X and 2X Phase Lag have available values of 0 to 359degrees.) Only the values available from the Recorder Outputs, CommunicationGateway and Display Interface Module are clamped to the specified value whenthe proportional value is invalid.

Recorder OutputThe proportional value of a channel that is sent to the 4 to 20 mA recorder. Therecorder output is proportional to the measured value over the channel full scalerange. An increase in the proportional value that would be indicated as upscaleon a bar graph display results in an increase in the current at the recorder output.

If 1X Phase Lag or 2X Phase Lag are selected then the two options available arewith and without Hysteresis. If the channel is Bypassed, the output will beclamped to the selected clamp value or to 2 mA (if the 2 mA clamp is selected).

The Hysteresis option helps prevent the Recorder Output from jumping from Fullto Bottom Scale when the phase measurement is near 0 or 359 degrees. Whenthe Hysteresis option is checked, the recorder signal operates as follows:

- The recorder output is scaled such that 4 mA corresponds to 0 degrees and 20mA corresponds to 380 degrees (360 plus 20 degrees).

DirectThe instantaneous eccentricity value. The direct value can be displayed threeways:

- At shaft rotative speeds greater than 600 rpm, the direct value is theaverage distance between the probe tip and the shaft and is displayed in away similar to a thrust measurement. This direct measurement isdisplayed only when Direct Channel Above 600 rpm is enabled.

- At shaft rotative speeds between 600 rpm and the rpm setting forInstantaneous Crossover, the direct measurement consists of two values:a maximum and minimum value relative to a zero reference. These twodirect values are called Direct Max and Direct Min.

- At shaft rotative speeds less than the rpm setting for InstantaneousCrossover, Direct Max and Direct Min are equal and the directmeasurement consists of an instantaneous measurement relative to azero reference. This type of direct measurement is called instantaneousgap.

NonlatchingIf a channel is configured for Nonlatching OK, the OK status of that channel willtrack the defined OK status of the transducer.

Timed OK Channel DefeatAn option that prevents a channel from returning to an OK status until that channel'stransducer has remained in an OK state for the specified period of time. If the optionis enabled, the time is set to 60 seconds. The option protects against false tripscaused by intermittent transducers.

3.1.6 Acceleration Channel OptionsThis section discusses the Configuration Considerations and the Rack ConfigurationSoftware screens associated with the Acceleration Channel.

3.1.6.1 Acceleration Channel Configuration ConsiderationsConsider the following items before configuring an Acceleration Channel:


- The Acceleration Direct full-scale range is dependent upon the transducer type.

- Monitors must be configured in channel pairs (for example, Channels 1 and 2 may


51

be configured as Acceleration and Channels 3 and 4 may be configured asRadial Vibration).



- When integration is selected, the available Direct Full-scale ranges will change toreflect this.

- When band-pass filtering is selected, the high-pass and low-pass filters must be seta minimum of two octaves apart.

- When two channels of acceleration are activated, the maximum channel frequencysupported is as shown:

Dual Channel Configuration Settings**Frequencies Filtering RMS Integration3 to 30 kHz No No No

10 to 30 kHz No Yes No3 to 9115 Hz Yes No No

10 to 9115 Hz --- --- Yes10 to 9115 Hz Yes Yes No

** Three dashes represent both yes and no

- When a single channel of acceleration is activated, the maximum channelfrequency supported is as shown:

Single Channel Configuration Settings**Frequencies Filtering RMS Integration3 to 30 kHz --- No No

10 to 30 kHz --- Yes No3 to 9115 Hz --- --- Yes

** Three dashes represent both yes and no


- Internal Barrier I/O Modules and External Barriers are not supported with highfrequency accelerometer transducers.

- Only 18 high frequency accelerometer transducers can be installed along with a fullrack of standard transducers. This is due to the fact that the rack can only power18 high frequency Accelerometer transducers.

3.1.8 Shaft Absolute Radial Vibration Channel OptionsThis section discusses the Configuration Considerations and the Rack ConfigurationSoftware screens associated with the Shaft Absolute Radial Vibration Channel.

3.1.8.1 Shaft Absolute Radial Vibration Channel Configuration Considerations

Consider the following items before configuring a Shaft Absolute Radial VibrationChannel:

- The Shaft Absolute Velocity channel type and the Shaft Absolute Radial Vibrationchannel type are configured in channel pairs, but the association of the particularshaft absolute proximity and velocity transducers is according to Group 1(channels 1 and 3) and Group 2 (channels 2 and 4).

- When "No Keyphasor" is selected, the 1X Amplitude (Ampl) and Phase Lag can notbe selected.


- The full scale options allowed for each proportional value is dependent upon thetransducer type.


- Setpoints may only be set on proportional values which are enabled.

- Monitors must be configured in channel pairs (for example, when channels 1 and 2are configured as Shaft Absolute Radial Vibration, Channels 3 and 4 must beconfigured as Shaft Absolute Velocity).



70

- It is best to set the Scale Factor value and the Trip Multiply value before the ZeroPosition value.

3.1.8.2 Shaft Absolute Radial Vibration Channel Configuration OptionsThis section describes the options available on the Shaft Absolute Radial VibrationChannel configuration screen.

Timed OK Channel DefeatThis prevents a channel from returning to an OK status until that channel'stransducer has remained in an OK state for 30 seconds. This feature is alwaysenabled in the Radial Vibration Channels. The option protects against false tripscaused by intermittent transducers.

CP ModSelecting the CP Mod button Channel Options Dialog Box, allows a Custom channelconfiguration to be downloaded to the monitor. Custom configuration data is storedin a Custom Products Modification File. Custom Products Modification files followthe naming convention <modification #.mod>. These files must be located in the\3500\Rackcfg\Mods\ directory. When a CP Mod file is selected, a window isdisplayed which describes the function of the modification. CP Mod files areavailable through Bently Nevada's Custom Products Division. Contact your localBently Nevada Sales Representative for details.


71


ChannelThe number of the channel being configured (1 or 2).

GroupThe association of channels which derive the shaft absolute signal. Group 1consists of channels 1 and 3, Group 2 consists of channels 2 and 4.



EnableAn enabled proportional value specifies that the value will be provided by thechannel ( enabled, disabled).

DirectData which represents the overall peak to peak vibration. All frequencies withinthe selected Direct Frequency Response are included in this proportional value.

GapThe physical distance between the face of a proximity probe tip and the observedsurface. The distance can be expressed in terms of displacement (mils,micrometres) or in terms of voltage. Standard polarity convention dictates that adecreasing gap results in an increasing (less negative) output signal.

Clamp ValueThe value that a proportional value goes to when that channel or proportionalvalue is bypassed or defeated (For example when a problem occurs with thetransducer). The selected value can be between the minimum and maximumfull-scale range values. (1X Phase Lag has available values of 0 to 359degrees.) Only the values available from the Recorder Outputs, CommunicationGateway and Display Interface Module are clamped to the specified value whenthe proportional value is invalid.


73

Recorder OutputThe proportional value of a channel that is sent to the 4 to 20 mA recorder. Therecorder output is proportional to the measured value over the channel full scalerange. An increase in the proportional value that would be indicated as upscaleon a bar graph display results in an increase in the current at the recorder output.

If 1X Phase Lag is selected then the two options available are with and withoutHysteresis. If the channel is Bypassed, the output will be clamped to theselected clamp value or to 2 mA (if the 2 mA clamp is selected).









If the 100 ms option is off ():- The Danger time delay can be set at one second intervals (from 1 to 60).- The Danger time delay can be set for up to two available proportional

values.

If the 100 ms option is on ():


74

- The Danger time delay is set to 100 ms.- The Danger time delay can only be set for the primary proportional value.

Zero Position (Gap)Represents the zero position (in volts) when the gap scale is to read the engineeringunits of displacement. To ensure maximum amount of zero adjustment, the probeshould be gapped as close as possible to the center gap voltage specified in the OKLimit table. This field is not available for Voltage Gap Scale.

Adjust ButtonAdjust the Zero Position voltage. When this button is clicked, a utility starts thathelps you set the gap zero position voltage. Since this utility provides activefeedback from the 3500 rack, a connection with the rack is required. Refer toSection 5.2 (Adjusting the Scale Factor and the Zero Position).

3.2 SetpointsThis section specifies the available setpoints for each type of channel. A setpoint isthe level within the full-scale range that determines when an alarm occurs. The3500 Monitoring System allows Alert/Alarm 1 setpoints to be set for everyproportional value on each channel. The channel will drive an Alert/Alarm 1indication if one or more of the channel proportional values exceeds its setpoints.The 3500 Monitoring System also allows up to four Danger/Alarm 2 setpoints (twoover setpoints and two under setpoints) to be set for up to two of the proportionalvalues. You may select any two of the available proportional values for the channel.

NoteThe setpoint over and under limits can only be placed within the OK limits ofthe specified transducer.

Use the following screen in the Rack Configuration Software to adjust Alert/Alarm 1and Danger/Alarm 2 setpoints. This screen will vary depending upon the type ofchannel.

5. MaintenanceThe boards and components inside of 3500 modules cannot be repaired in thefield. Maintaining a 3500 rack consists of testing module channels to verify thatthey are operating correctly. Modules that are not operating correctly should bereplaced with a spare.

When performed properly, this module may be installed into or removed from therack while power is applied to the rack. Refer to the Rack Installation anMaintenance Manual (part number 129766-01) for the proer procedure.

This section shows how to verify the operation of channels in anProximitor/Seismic Monitor (Section 5.1), how to adjust the scale factor(Section 5.2.1), and zero position (Section 5.2.2).

5.1 Verifying a 3500 Rack - Proximitor /SeismicMonitor ModuleThe 3500 Monitoring System is a high precision instrument that requires nocalibration. The functions of monitor channels, however, must be verified atregular intervals. At each maintenance interval, we recommend that you use theprocedures in this section to verify the operation of all active channels in themonitor. It is only necessary to verify the alarms and accuracy of channelproportional values that are active.

5.1.1 Choosing a Maintenance IntervalUse the following approach to choose a maintenance interval:

Start with an interval of one year and then shorten the interval if any of thefollowing conditions apply:- the monitored machine is classified as critical.- the 3500 rack is operating in a harsh environment such as in extreme

temperature, high humidity, or in a corrosive atmosphere.

At each interval, use the results of the previous verifications and ISOProcedure 10012-1 to adjust the interval.

5.1.2 Required Test EquipmentThe verification procedures in this section require the following test equipment.

• RS


122

Transducers can be connected to a 3500 rack in a variety of ways. Dependingon the wiring option for the I/O module of your monitor, connect the testequipment to the monitor using one of the following methods:

5.1.4 Using the Rack Configuration SoftwareThe laptop computer that is part of the test setup uses the Rack ConfigurationSoftware to display output from the rack and to reset certain operatingparameters in the rack. To perform the test procedures in this section you mustbe familiar with the following features of the Rack Configuration Software:

- upload, download, and save configuration files

- enable and disable channels and alarms

- bypass channels and alarms

- display the Verification screen

The Rack Configuration and Test Utilities Guide (part number 129777-01)explains how to perform these operations.

NoteIt is important to save the original rack configuration before doing anyMaintenance or Troubleshooting Procedures. It may be necessary duringthese procedures to change setpoints, etc. which must be restored to theiroriginal values at the conclusion of the procedures. At that time the originalconfiguration should be downloaded to the rack.

5.1.5.2 Test Alarms - Radial VibrationThe general approach for testing alarm setpoints is to simulate the vibration andKeyphasor® signal with a function generator. The alarm levels are tested byvarying the vibration signal (both peak to peak amplitude and DC voltage bias)and observing that the correct results are reported in the Verification screen onthe test computer. It is only necessary to test those alarm parameters that areconfigured and being used. The general test procedure to verify current alarmoperation will include simulating a transducer input signal and varying this signal:1. to exceed over Alert/Alarm 1 and Danger/Alarm 2 Setpoints, and2. to drop below any under Alert/Alarm 1 and Danger/Alarm 2 Setpoints and3. to produce a nonalarm condition.

When varying the signal from an alarm condition to a nonalarm condition, alarmhysteresis must be considered. Adjust the signal well below the alarm setpointfor the alarm to clear.

NoteUse the Transducer Scale Factor displayed in the Scale Factor Box on theVerification Screen.

Example 1:Direct Meter Top Scale = 10 milTransducer Scale Factor = 200 mV/mil

Full Scale = (10 × 0.200)= 2.000 Vpp

For Vrms input:Vrms = (0.707/2) × (Vpp), for a sinewave input

Example 2:Direct Meter Top Scale = 200 µmTransducer Scale Factor = 7,874 mV/mm

= 7.874 mV/µm

Full Scale = (200 × 0.007874)= 1.5748 Vpp

1. Disconnect PWR, COM, and SIG field wiring from the channel pair terminalson the I/O module.

2. Connect test equipment and run software as described in Section 5.1.5.1(Test Equipment Setup - Radial Vibration ). Smax requires inputconnections to both channel 1 and 2 or channel 3 and 4.

3. Calculate the full-scale voltage using the equation and example shownbelow.

Full-Scale Voltage =(Smax Meter Top Scale × Transducer Scale Factor) × 1.414


Example 1:Smax Meter Top Scale = 10 milTransducer Scale Factor = 200 mV/mil

Full Scale = (10 × 0.200) × 1.414= 2.828 Vpp

For Vrms input:


150

Vrms = (0.707/2) × (Vpp), for a sinewave input= (0.707/2) × (2.828)= 0.999 Vrms

Example 2:Smax Meter Top Scale = 200 µmTransducer Scale Factor = 7,874 mV/mm

= 7.874 mV/µmFull Scale = (200 × .007874) × 1.414

= 2.2267 Vpp


= (0.707/2) × (2.2267)= 0.7871 Vrms

4. Set the Keyphasor multiplier/divider so that the multiply setting is set to oneand the divide setting is set to one. Adjust the function generator amplitudefor full scale. Verify that the Smax bar graph display and Current Value Box isreading ±1 % of full scale. If the recorder output is configured, refer toSection 5.1.12 (Verify Recorder Outputs) for steps to verify the recorderoutput.


6. Disconnect the test equipment and reconnect the PWR, COM, and SIG fieldwiring to the channel pair terminals on the I/O module. Verify that the OKLED comes on and the OK relay energizes. Press the RESET switch on theRack Interface Module (RIM) to reset the OK LED.


5.1.5.4 Test OK LimitsThe general approach for testing OK limits is to input a DC voltage and adjust itabove the Upper OK limit and below the Lower OK limit. This will cause achannel not OK condition and the OK Relay to change state (de-energize). TheUpper and Lower OK limits are displayed in the Verification screen on the testcomputer.



3. Bypass all other configured channels.


151

4. Adjust the power supply voltage to -7.00 Vdc.

5. Press the RESET switch on the Rack Interface Module (RIM). Verify that themonitor OK LED is on and that the Channel OK State line in the ChannelStatus box of the Verification screen reads OK.

NoteIf the Danger Bypass has been activated, then the BYPASS LED will be on.All other channels in the rack must be OK or bypassed for the relay to beenergized.

6. Verify that the OK relay on the Rack Interface I/O Module indicates OK(energized). See 3500/20 Rack Interface Module Operation andMaintenance Manual, part number 129768-01.

7. Increase the power supply voltage (more negative) until the OK LED justgoes off (upper limit). Verify that the Channel OK State line in the ChannelStatus box reads not OK and that the OK Relay indicates not OK. Verify thatthe Upper OK limit voltage displayed on the Verification screen is equal to ormore positive than the input voltage.

8. Decrease the power supply voltage (less negative) to -7.00 Vdc.

9. Press the RESET switch on the Rack Interface Module (RIM). Verify that theOK LED comes back on and the OK relay energizes. Verify that the ChannelOK State line in the Channel Status box reads OK.

10. Gradually decrease the power supply voltage (less negative) until the OKLED just goes off (lower limit). Verify that the Channel OK State line in theChannel Status box reads not OK and that the OK Relay indicates not OK.Verify that the Lower OK limit voltage displayed on the Verification screen isequal to or more negative than the input voltage.

11. Increase the power supply voltage (more negative) to -7.00 Vdc.

12. Press the RESET switch on the Rack Interface Module (RIM). Verify that theOK LED comes back on, the OK relay energizes and that the Channel OKState line in the Channel Status box reads OK.

13. If you can not verify any configured OK limit, go to Section 5.1.13 (If aChannel Fails a Verification Test).

14. Disconnect the test equipment and reconnect the PWR, COM, and SIG fieldwiring to the channel terminals on the Monitor I/O Module. Press the RESETswitch on the Rack Interface Module (RIM) and verify that the OK LED comeson and the OK relay energizes.


16. Return the bypass switch for all configured channels back to their originalsetting.

3. Calculate the full-scale and bottom scale values. These values can becalculated in the following way:

Full-scale Value, Bottom Scale Value =Zero Position Voltage ± (Transducer Scale Factor × Scale Range)

NoteThe Zero Position Voltage is the voltage input that will cause the reading onthe bar graph display and the Current Value Box to be zero. The Zero PositionVolts value is displayed in the Z.P. Volts box above each channel value bargraph.

NoteIf the bottom scale range is zero (for example 0 to 80 mil), use the Full-scaleValue formula.


If Upscale direction (Normal for Thrust, Long for Differential Expansion) is towardthe probe:

Full Scale =(Zero Position Voltage) + (Transducer Scale Factor × Top Meter Scale)

Bottom Scale =(Zero Position Voltage) - (Transducer Scale Factor × ABS (Bottom MeterScale)

Example 1:Transducer scale factor = 200 mV/milMeter scale range = 25-0-25 milZero Position Voltage = -9.75 Vdc

Full Scale Value = (-9.75) + (0.200 × 25)= -4.75 Vdc

Bottom Scale Value = (-9.75) - (0.200 × 25)= -14.75 Vdc

Example 2:Transducer scale factor = 7,874 mV/mmMeter scale range = 1-0-1 mm


159

Zero Position Voltage = -10.16 Vdc

Full Scale Value = (-10.16) + (7.874 × 1)= -2.286 Vdc

Bottom Scale Value = (-10.16) - (7.874 × 1)= -18.03 Vdc

If Upscale direction (Normal for Thrust, Long for Differential Expansion) is awayfrom the probe:

Full Scale =(Zero Position Voltage) - (Transducer Scale Factor × Top Meter Scale)

Bottom Scale =(Zero Position Voltage) + (Transducer Scale Factor × ABS(Bottom MeterScale)


Full Scale Value = (-9.75) - (0.200 × 25)= -14.75 Vdc

2. Connect test equipment:

For Seismoprobe:Connect test equipment and run software as described in section 5.1.8.1(Test Equipment and Software Setup - Velocity), use the setup shown onpage 178 (Seismoprobe Test Setup). If no filtering has been configured,leave the frequency of the function generator set to 100 Hz. If filtering isconfigured, the needed frequency can be calculated from the followingformula:

Frequency = (0.89 × HPF) + (0.1575 × LPF)

HPF = High-pass Filter Corner FrequencyLPF = Low-pass Filter Corner Frequency

If no filtering is configured, set the frequency of the function generator to 100Hz.

5.1.8.7 Test OK Limits - Velocity


For Seismoprobes:The general approach for testing OK limit is to disconnect the input. This willcause a not OK condition and the OK Relay to change state (de-energize).

1. Run the Verification Software as described in Section 5.1.8.1 (TestEquipment and Software Setup - Velocity).

2. Disconnect the SIG / A field wiring from the channel terminals on theProximitor / Seismic Monitor I/O Module.

3. Verify that the OK relay changes state (de-energized).

4. Verify that the Channel OK State line on the Verification screen reads notOK.

5. Reconnect the SIG / A field wiring to the channel terminals on the Monitor I/OModule. Press the RESET switch on the Rack Interface Module (RIM) andverify that the OK LED comes on and the OK relay energizes.

6. Verify that the Channel OK State line on the Verification screen reads OK.



For Velomitors with Proximitor/Seismic I/O Modules:The general approach for testing OK limits is to input a DC voltage and adjust itabove the Upper OK limit and below the Lower OK limit. This will cause a notOK condition and the OK Relay to change state (de-energize). The Upper andLower OK limits are displayed in the Verification screen on the test computer.

1. Disconnect PWR / B, COM, and SIG / A field wiring from the channelterminals on the I/O module.

2. Connect test equipment and run software as described in Section 5.1.8.1(Test Equipment and Software Setup - Velocity), page 180.

Verify that the Lower OK limit voltage displayed on the Verificationscreen is equal to or more negative than the input voltage.


12. Press the RESET switch on the Rack Interface Module (RIM). Verify that theOK LED comes back on, the OK relay energizes, and the Channel OK Stateline in the Channel Status section reads OK.


14. Disconnect the power supply and multimeter and reconnect the PWR, COM,and SIG field wiring to the channel terminals on the Monitor I/O Module.Press the RESET switch on the Rack Interface Module (RIM) and verify thatthe OK LED comes on and the OK relay energizes.



For Velomitors with Proximitor/Velomitor or TMR I/O Modules:Due to the requirements for increased robustness in the TMR system, the TMRI/O Module has a Velomitor interface that is different from the Prox/Seis I/OModule's Velomitor interface. The Proximitor/Velomitor I/O Module shares thisfeature with the TMR I/O. The effect of this difference is that the Velomitor signalinput to the I/O Module is 180 degrees out of phase from the correct Velomitorsignal. This inversion is compensated for in the TMR and Proximitor/Velomitor


194

I/O Module. This means that when you input a test signal using a signalgenerator or DC power supply the buffered outputs on the front panel will beinverted in phase and will have a different DC voltage than the input. This willnot affect the actual vibration readings in the Monitor.

5.1.10.3 Verify Channel Values – Shaft Absolute Radial VibrationThe general approach for testing channel values is to simulate the vibration andKeyphasor input signal with a function generator. The output values are verifiedby varying the input vibration signal level (both peak to peak amplitude and DCvoltage bias) and observing that the correct results are reported in theVerification screen on the test computer.

NoteThese parameters have an accuracy specification of ±1 % of full scale foramplitude and ±3 degrees for phase.

Direct



3. Calculate the full-scale voltage according to the equation and examplesshown below. Adjust the amplitude of the function generator to thecalculated voltage.

Full Scale Voltage = Direct Meter Top Scale × Transducer Scale Factor


Example 1:Direct Meter Top Scale = 10 milTransducer Scale Factor = 200 mV/mil

Full Scale = (10 × 0.200)= 2.000 Vpp

Example 2:Direct Meter Top Scale = 200 µmTransducer Scale Factor = 7,874 mV/mm

= 7.874 mV/µm

Full Scale = (200 × 0.007874)= 1.5748 Vpp

4. Set the Keyphasor multiplier/divider so that the multiply setting is one and thedivide setting is one. Verify that the Direct bar graph display and CurrentValue Box is reading ±1 % of full scale. If the recorder output is configured,refer to Section 5.1.12 (Verify Recorder Outputs ) for steps to verify therecorder output.

3. If Gap is configured to read in volts , adjust the power supply to produce avoltage equal to -18.00 Vdc on the Gap bar graph display. Verify that theGap bar graph display and Current Value Box is reading ±1 % of -18.00 Vdc.If the recorder output is configured, Refer to Section 5.1.12 (Verify RecorderOutputs ) for steps to verify recorder output.

4. Adjust the power supply to produce a voltage equal to mid-scale on the Gapbar graph display. Verify that the Gap bar graph display and Current ValueBox is reading ±1 % of the mid-scale value. If the recorder output isconfigured, refer to Section 5.1.12 (Verify Recorder Outputs ) for steps toverify the recorder output. Go to step 8.

If Gap is configured to read in displacement units , calculate the full-scale andbottom-scale voltage using the following equation:


Gap Full-Scale =Gap Zero Position Volts + (Gap Meter Top Scale × Transducer Scale Factor)

Example 1:Transducer Scale Factor = 200 mV/milScale Range is 15-0-15 mil (Gap Top Scale = 15 mil)Gap Zero Position Volts = -9.75 Vdc



221


= 7.874 mV/µmScale Range is 300-0-300 µm (Gap Top Scale = 300 µm)Gap Zero Position Volts = -9.75 Vdc


Gap Bottom-Scale =Gap Zero Position Volts - (Gap Meter Bottom Scale × Transducer Scale

Factor)

Example 1:Transducer Scale Factor = 200 mV/milScale Range is 15-0-15 mil (Gap Bottom Scale = 15 mil)Gap Zero Position Volts = -9.75 Vdc



= 7.874 mV/µmScale Range is 300-0-300 µm (Gap Bottom Scale = 300 µm)Gap Zero Position Volts = -9.75 Vdc


5. Adjust the power supply voltage to match the voltage displayed in the GapZero Position Volts Box. The Gap bar graph display and Current Value Boxshould read 0 mil (0 mm) ±1 %.

6. Adjust the power supply to produce a voltage equal to top scale (from step 3)on the Gap bar graph display. Verify that the Gap bar graph display andCurrent Value Box is reading ±1 % of top scale. If the recorder output isconfigured, refer to Section 5.1.12 (Verify Recorder Outputs ) for steps toverify recorder output.

5.1.11.3 Verify Channel Values - VelocityThe general approach for testing these parameters is to simulate the velocitysignal with a function generator and power supply. The Shaft Absolute RadialVibration signal (channels 1 or 2) will be zero, making the shaft absolute signalequal to the integrated velocity signal. The channel values are verified byvarying the output from the test equipment and observing that the correct resultsare reported in the Verification screen on the test computer.

NoteThese parameters have an accuracy specification of ±1 % of full-scale.

Shaft Absolute Direct (SA DIR)

1. Disconnect PWR, COM, SIG, SEIS / A, and SEIS/B field wiring from thechannel group terminals on the I/O module.

2. Connect test equipment and run software as described in section 5.1.11.1(Test Equipment and Software Setup – Shaft Absolute Velocity). Use theappropriate transducer drawing, either Seismoprobe Channel VerificationTest Setup or Velomitor® Channel Verification Test SetupTest Setup.

3. Adjust the function generator frequency to 100 Hz.

4. Adjust the function generator (sinewave) amplitude to 100 Hz.

Verify that the OK LED comes on and the OK relay energizes. Press theRESET switch on the Rack Interface Module (RIM) to reset the OK LED.


Shaft Absolute 1X Phase (SA 1X PH)






4. Measure the phase. 1X Phase will be measured from the leading edge of theKeyphasor® pulse to the first positive peak of the vibration signal. Since theShaft Absolute 1X signal is determined after integration of the velocity signal,you must subtract 90° from the phase measured with the input signal. Seethe example below (on page 224) which illustrates a phase of 45°. Aftersubtracting 90°, the phase will be 45° – 90° = -45°, or 315° . Observe the 1XPhase bar graph display and Current Value Box; it should read approximatelywhat was measured above, minus 90°.

To reduce this influence, measurethe amplitude of the input test signal between this capacitor and the ShaftAbsolute I/O module.





252

5.1.11.5 Calculating the Input Voltage for Full-scaleThe procedures for verifying channel values and corner frequencies require thatyou use the following formulas to calculate the input voltage for Full-scale. Tofind the Full-scale input voltage, use appropriate table or formula for integrated ornon-integrated units.

NoteUse the Transducer Scale Factor displayed in the Scale Factor Box on theVerification screen.


Units To Input Peak to Peak Volts

in/s pk (T.S.F x Full-scale) x 2

mm/s pk (T.S.F x Full-scale) x 2

To use the formulas, the T.S.F. should be in volts and the T.S.F andfull-scale values should both be of the same unit system (metric orEnglish). The transducer Scale Factor will always be specified asvolts per inch/second pk or volts per millimetre/second pk.

Example 1:Transducer Scale Factor = 500 mV/(in/s)Full Scale = 0.5 in/s pk

For Peak to Peak input:(0.500 × 0.5) × 2 = 0.5 Vpp

Example 2:Transducer Scale Factor = 19.69 mV/(mm/s)Full Scale = 20 mm/s pk



253

Full Scale Formulas - Integration (For the following units: mil pp and µm pp)

To use the formulas, the Velocity Scale Factor should be in volts, and the Full-scale value and Velocity Scale Factor should be in English units. Use thefollowing conversion formulas to convert Metric units to English units:

5.1.11.6 Test OK Limits - Velocity


For Seismoprobes:The general approach for testing OK limits is to disconnect the input. This willcause a not OK condition and the OK Relay to change state (de-energize).

1. Run the verification software as described in section 5.1.11.1 (TestEquipment and Software Setup – Shaft Absolute Velocity).

2. Disconnect the SEIS / A field wiring from the channel group terminals on theShaft Absolute I/O Module.

3. Verify that the OK relay changes state (de-energized).

4. Verify that the Channel OK State line on the Verification screen reads notOK.

5. Reconnect the SEIS / A field wiring to the channel terminals on the MonitorI/O Module. Press the RESET switch on the Rack Interface Module (RIM)and verify that the OK LED comes on and the OK relay energizes.

6. Verify that the Channel OK State line on the Verification screen reads OK.



For Velomitors with Shaft Absolute I/O Modules:Due to the requirements for increased robustness in the system, the ShaftAbsolute I/O Module has a Velomitor interface that is different from the Prox/SeisI/O Module's Velomitor interface. The Shaft Absolute I/O Module shares thisfeature with the TMR I/O and Proximitor/Velomitor I/O module. The effect of thisdifference is that the Velomitor signal input to the I/O Module is 180 degrees outof phase from the correct Velomitor signal. This inversion is compensated for inthe Shaft Absolute, TMR, and Proximitor/Velomitor I/O Modules. This meansthat when you input a test signal using a signal generator or DC power supplythe buffered outputs on the front panel will be inverted in phase and will have adifferent DC voltage than the input. This will not affect the actual vibrationreadings in the Monitor.

The general approach for testing OK limits is to input a DC voltage and adjust itabove the Upper OK limit and below the Lower OK limit. This will cause a not


256

OK condition and the OK Relay to change state (de-energize). The Upper andLower OK limits are displayed in the Verification screen on the test computer.

1. Disconnect SEIS / A, and SEIS / B field wiring from the channel group terminals on the I/Omodule.

2. Connect test equipment and run software as described in Section 5.1.11.1(Test Equipment and Software Setup – Shaft Absolute Velocity, Velomitor®OK Limit Test Setup), page 234.





7. Increase the power supply voltage (more negative) until the OK LED justgoes off (lower limit due to the inversion on the I/O Module). Verify that theChannel OK State line on the Verification screen reads not OK and that theOK Relay indicates not OK. Verify that the Lower OK limit voltage displayedon the Verification screen is equal to or more negative than the followingvalue.

For the Shaft Absolute I/O Module:

Vinput - - Voltage Limit

OK Lower90.16≤



10. Gradually decrease the power supply voltage (less negative) until the OKLED just goes off (upper limit due to the inversion on the I/O Card). Verifythat the Channel OK State line in the Channel Status section reads not OKand that the OK Relay indicates not OK. Verify that the Upper OK limitvoltage displayed on the Verification screen is equal to or more positive thanthe following value.


257

For the Shaft Absolute I/O Module:

5.2 Adjusting the Scale Factor and the ZeroPositionThis section shows how to adjust the transducer scale factor and the transducerposition, or "zero". The Scale Factor Adjustment can be used to accommodateany deviations in transducer scale factor as measured on the installedtransducers. Do not use the procedure to compensate for any errors within themonitor and the I/O module. If a monitor does not meet specifications, exchangeit with a spare and return the faulty module to Bently Nevada Corporation forrepair. The newly installed spare module should be properly configured andtested.

Adjusting the scale factor affects the readings of all configured parametersassociated with the channel. If you change the scale factor, be sure to use thenew value when calculating inputs for verification of channel values.

The Zero Position Adjustment is used for Thrust, Eccentricity, and DifferentialExpansion measurements as well as for Gap measurements when Gap isconfigured to read in displacement units (not volts). Adjust the zero position afterthe probe is gapped and its target is in the proper position.

Both adjustment procedures consist of using the Rack Configuration Software toupload the configuration from the rack, change the setting for scale factor or zeroposition, and then downloading the new configuration back to the rack. You canadjust these settings using the following two methods:

enter a new value in the scale factor box on the transducer screen or the zeroposition box on the Channel Options screen.

use Adjust to get immediate feedback from the channel on the Adjust screen.

The advantage of using the Adjust screen is that you can use the bar graphs tosee the effect of your adjustments on the output signals of the channel. Thefollowing procedures show how to use the methods.

5.2.1 Adjusting the Scale Factor1. Connect the configuring computer to the rack using one of the methods listed

in the 3500 Monitoring System Rack Configuration and Utilities Guide (partnumber 129777-01).

2. Run the Rack Configuration Software.

3. Initiate communication with the rack by clicking on the Connect option in theFile menu and then selecting the connection method that you used in step 1.

4. Upload the configuration from the rack by clicking on the Upload option in theFile menu.

5. Click on the Options button on the 3500 System Configuration screen.


261

6. Select the monitor you want to adjust. The Monitor screen will appear.

7. Select the Options button under the appropriate Channel. The configuredChannel Options screen will appear.

8. Select the Customize button in the Transducer Selection box. A Transducerscreen will appear.

9. Enter a value for scale factor in the Scale Factor box. If you go to the Adjustscreen by selecting Adjust , be sure to adjust the input to the channel awayfrom the Zero Position so you can adjust the scale factor and see the results.

10. Return to the 3500 System Configuration screen by clicking on the OKbuttons of the successive screens. The new scale factor is now added to theconfiguration for this channel.

11. Download the new configuration to the appropriate monitor by selectingDownload from the File menu. The new setting for scale factor will takeeffect when the "Download successful" prompt appears.

5.2.2 Zero Position Adjustment Description

When adjusting the Zero Position voltage, you aredefining the transducer voltage corresponding to theposition of the zero indication on a bar graph display(refer to the adjacent figure).

For maximum amount of zero adjustment, gap thetransducer as close as possible to the ideal zeroposition voltage based on the full-scale range andtransducer scale factor. For a mid-scale zero, as inthe example, the ideal gap is the center of the range.The tables below specify the center of the range foreach transducer and monitor type. -25

5.3 Performing Firmware Upgrades

Occasionally it may be necessary to replace the original firmware that is shippedwith the 3500/42M Proximitor Monitor. The following instructions describe how toremove the existing firmware and replace it with upgrade firmware. The monitorwill need to be reconfigured using the 3500 Rack Configuration software afterhaving its firmware upgraded.

The following items will be required to perform a firmware upgrade to themonitor:

Large Flathead Screwdriver.

Grounding Wrist Strap.*

IC Removal Tool.*

Upgrade Firmware IC.*

*Refer to Section 7 for part numbers. Users may use their own grounding wriststrap or IC removal tool.

5.3.1 Installation ProcedureThe following steps will need to be followed to complete the monitor firmwareupgrade:

Ensure that the monitor’s configuration is saved using the 3500 RackConfiguration software.

Refer to Section 1.2 before handling the monitor or the upgrade firmware IC.

Remove the monitor from the 3500 rack.

Acceleration Frequency Response

The following table represents the frequency ranges for the 3500/42M underdifferent filtering options. Resources used for filtering are assigned basedon channel pairs. It is possible to select different filtering options for the twochannels of a channel pair. However, the frequency response for bothchannels will be limited to the worst case frequency response of theindividual channels. If added frequency range is required, the 3500/42Mcan be configured as a two-channel monitor (use channels 1 and 3). Thislets you combine the resources normally used for filtering of two channelsand use them for one. See page 51

ALARMS

Alarm Setpoints: Alert levels can be set for each valuemeasured by the monitor. In addition,Danger setpoints can be set for any two ofthe values measured by the monitor. Allalarm setpoints are set using softwareconfiguration. Alarms are adjustable andcan normally be set from 0 to 100 % of FullScale for each measured value. Theexception is when the Full Scale rangeexceeds the range of the transducer. In thiscase, the set point will be limited to therange of the transducer. Accuracy of alarmsare to within 0.13 % of the desired value.

Alarm Time Delays:

Alert:

Danger:

Alarm delays can be programmed usingsoftware, and can be set as follows:

From 1 to 60 seconds in 1 second intervals.

0.1 seconds (typical) or from 1 to 60seconds in 1 second intervals.
